Therapist for Deaf adults or children?

I've always wanted to be a therapist. Probably either a psychologist or an occupational therapist, however I'm open to other ideas. I have a pion for sign language. I'm currently learning it. My teacher is deaf and I love getting to take a peak into the culture she's sharing with me. I'm involved with the Deaf community in my town and would love to adopt Deaf children one day. Anyways, I want a job as a therapist but I also want to be able to use ASL in my work. Is that possible? What do you think? I would appreciate any knowledge from you as a fellow signer (deaf or hearing) thanks!
